Guinness World Records has recognized the University of Texas at San Antonio for creating the world's smallest medical robot.
The researchers developed nanocomposite particles that can be remotely controlled by an electromagnetic field, and function in the manner of extremely tiny robots that interact with biological cells.
The nanocomposites are made from two different types of multifunctional oxide materials in a "core and shell" configuration. The core is magnetic and changes shape in response to magnetic fields, while the shell is ferroelectric and converts pressure into electric potentials. These aspects of the system act as arms and legs that move the nanoparticle around to interact with targeted biological cells.
The nanorobots can move cells to align with one another, push cells into different locations, and potentially be used to deliver medication to a cell.
